Your Dodge oxygen sensor is a smartly engineered automotive device, serving to both monitor the combustion system, helping the main computer of your vehicle to keep that system functioning at its most efficient, and to help control the amount of pollutants released into the air as a result of the fuel burning that is essential to the ability of the internal combustion engine to produce power. You'll find your Dodge oxygen sensor in the exhaust system of your vehicle, and as suggested by its name, it measures the amount of oxygen remaining in the exhaust fumes after they exit the combustion system. If there is too much or too little oxygen, the Dodge oxygen sensor relays that data to the main computer, which then adjusts the air-to-fuel ratio in an effort to achieve the most efficient balance possible. When the air-to-fuel ratio is off, not only is your vehicle not going to be running at its best or most efficient, running the risk of damaging parts within the combustion system and exhaust system, but it will also be unnecessarily adding more pollutants to the air that we all breathe. Poor engine performance and reduced fuel mileage are a couple signs that your Dodge oxygen sensor may be starting to falter. When your Dodge oxygen sensor has begun to malfunction, it is best to attend to it promptly, as it can place your catalytic converter at risk of failing long before its time, overwhelmed by heavy exhaust gasses.
